Class VersionUtil

  com.fasterxml.jackson.core.util.VersionUtil

Direct Known Subclasses:

CoreVersion

public class VersionUtil
extends Object

Functionality for supporting exposing of component Versions.

Note that this class can be used in two roles: first, as a static utility class for loading purposes, and second, as a singleton loader of per-module version information. In latter case one must sub-class to get proper per-module instance; and sub-class must reside in same Java package as matching "VERSION.txt" file.

Method Detail

version

public Version version()

versionFor

public static Version versionFor(Class<?> cls)

Helper method that will try to load version information for specified class. Implementation is simple: class loader that loaded specified class is asked to load resource with name "VERSION" from same location (package) as class itself had. If no version information is found, Version.unknownVersion() is returned.

mavenVersionFor

public static Version mavenVersionFor(ClassLoader classLoader,
                                      String groupId,
                                      String artifactId)

Will attempt to load the maven version for the given groupId and artifactId. Maven puts a pom.properties file in META-INF/maven/groupId/artifactId, containing the groupId, artifactId and version of the library.

Parameters:

classLoader - the ClassLoader to load the pom.properties file from

groupId - the groupId of the library

artifactId - the artifactId of the library

Returns:

The version

parseVersion

@Deprecated
public static Version parseVersion(String versionStr)

Deprecated.

Use variant that takes three arguments instead

parseVersion

public static Version parseVersion(String versionStr,
                                   String groupId,
                                   String artifactId)

parseVersionPart

protected static int parseVersionPart(String partStr)
